IMPROVEMENT IN ELASTIC TRUSSES.

Specification forming part of Let-ters Patent No. 196,272, dated October16, 1877 application filed I June 11, 1877.

To all whom it may concern:

Be it known that we, GEORGE A. TYER and WALTER J. HORNE, both of thecity and coimty of San Francisco, State of California, have made andinvented certain new and useful Improvements in Elastic Trusses, whichimprovements are fully set forth in the following specification andaccompanying drawing.

In the said drawing, Figure l is a front view of our improved truss.Fig. 2 is a detail view of the pad, padplates, and centralsupporting-springs. Fig. 3 is a sectional view through the pad-pl atesand spring. Fig. 4 is a detail view of the snaps and holding-plate.

Our invention has for its obj eet to produce a self-adjusting truss, inwhich the pad shall have the capacity to yield in or to all positionsand motions of the body, and at the same time to hold securely in placeand bear against the rupture with a regular pressure, and when onceadjusted to the form and size of the wearer the truss or pad can betaken off and put on without disturbing or changing thelength andadjustment of the elastic bands or straps, as will be fully set forthhereinafter.

Itconsists in the construction of the padplates with a conical springbetween them, held in place by a central bolt upon which thestrap-holding plate turns and rocks as a center, and with a screw-sleeveupon the under side of the lower plate, which holds the pad in place andallows it to be taken off and replaced without disturbing the otherparts.

The straps are provided with snap-hooks, which engage with the slots inthe projecting ears of the upper plate, and the pad is held in thismanneragainst the person with the capacity to yield with the body.

In the drawings, A represents the pad; B,

its plate, with the screw-sleeve b C, the conical metal spring; D, aplate bearing upon the apex of the spring. E is the upper holdingplate,with its oblong or rectangular slots so, to receive the snaps F F on theends of the strap and band G H.

bolt serves as a pivot or swivel for the holdingplate E, and also actsto keep the spring in place and to compress it to the required degree.

The conical form of the spring 0 affords a broad and stable base, and atthe same time allows the pad to yield and take any angle with theholding-plate, and forms a perfect swivel-joint.

Instead of having the straps or bands connected directly and permanentlyto it, the ends of the straps attach to the pad plate E by means of thesnap-hooks F F, one for the waist-strap and one for the perineal strap.These hooks engage with the slots or loops 0 c on the plate E, andadjust themselves to the position of the pad according as it is situatedhigh or low.

The lengths of A the straps G H are adjustable by means of the buckles gh, and when their length is once regulated the pad can be taken oif andchanged, or the truss put on and removed by the wearer, withoutassistance, at any time of day or night, by means of the snap-hooks, bywhich the trouble and annoyance of adjusting the truss every time isavoided and overcome.

The pad A being secured to the lower plate B independent of any screwallows the pads to be readily changed without interfering with theadjustment and arrangement of the other parts with each other.

This truss is readily adapted to be used either for a right-hand or aleft-hand rupture.

Having thus fully described our invention, what we claim, and desire tosecure'by Letters Patent as being new therein, is

The combination, with the pad A, of the plate B, provided withscrew-sleeve b, the conical volute springs C, the plate D, strap-holdingplate E, and the center-bolt (0, having an adjusting-nut at one end,constructed and arranged substantially as described and shown.

In testimony that we claim the foregoing we have hereunto set our handsthis 24th day of May, 1877.
